' UNITED sures PATENT OFFIC FUEL comfrfitfifiw DEVICE Y I Elnar N. So ensen, F rnandina, Flat Application Mitch 8, 1935, sGl'lal N0. 10,065 6 aims. (01. 257-232) One of these removable sides is provided with a nipple for connecting to a pipe from the carburetor; and another or-the removable sides is riming device such as will be The fixed or nondrawing funnmay be plain as indicated. These plates are removable and interchangeably held in position as by screws l1.

In installing the device the housing may be positioned in any suitable, convenient place and the nipple I connected to the intake manifold. The removable and interchangeable sides may then be positioned on the sides of the housing where the nipple 12 will be in the most siutable position for attachment to the carburetor, and the priming device 43 arranged in convenient position.

As my invention is for use in conjunction with heavy distillates which cannot be used as fuel for internal-combustion engines until highly heated, it is evident that means must he provided ior starting and initially running the engine until the conditioning. necessary temperature. It is for this reason that I provide the priming device 53 so that a quantity of gaso line may be admitted to the housing i which will be vaporized as the air, with the particles of the distillatcs are received from the carburetor. This will form an explosive mixture of sumcient richness to start the engine and maintain the same in operation until the conditioner is heated sumciently to gasifythe iuel distillate.

In order to utilize the maximum oi the heat passing from the a plurality of spurs through the walls of said duct with one end projecting into the passageway oi the duct t and the other and projecting into the housing. These spurs may be of various forms as illustrated in in Fig. i these spurs transversely flat ends is are preferably arranged at an angle,

as indicated so as to deflect the gases into a substantially spiral course as they pass through the housing. It preferred screws 2i such as shown duct 4; or tapered pins 22 such as shown in Fig. 6 may be driven into position after the duct has been suitably drilled.

A device as disclosed herein is designed for the purpose of using heavy distillates for fuel such as cannot be used with an ordinarily equipped internal-combustion engine; and it should not be confused with the heaters w ch are designed to merely heat volatile ruels, particularly in cold weather or under adverse conditions. when using' such distillates, the housing must be maintained at a very high temperature and as a result of such high temperature and the nature of the fuel, the spurs between the duct 3 and the walls or the housing, together with the outer surface of the duct 1, soon become coated with carbon, which necessitates comparative irequent cleaning of the device. It'is primarily for this reason that the housing is provided with the several removable sides as without which it would be impossible to use the heavy distillates as fuel. Unless means are provided for ready access to the housing i5, it would be practically impossible to use a heavy distillate as oil, as within a short time the device-would become inemcient and cease to operate. By having the removable sides interchangeable and equipped as mentioned, the device also lends itself to being positioned in any convenient place relative to the engine with which it is to he used.

I claim:

1. A conditioning device for distillates comprising a housing equipped with means for connecting the some to the intake manifold oi an englue and to a carburetor, an exhaust gas duct extending thercthrough, means on said duct for increasing the radiation thereof, and said housing provided with removable sides, as and for the purpose specified.

2. A device as set forth in claim 1 in which the removable sides are interchangeable and in which the means for connection to the carburetor is formed on. one or said removable sides, substantially as described.

3. A device as set iorth in claim removable sides are interchangeable, one oi said sides being equipped with the means for connection to the carburetor, and priming means on an- L other or" said removable and interchangeable sides, as and the purpose specified.

i. A conditioning device for distiliates comprising a. housing provided with means for connecting the same to an intake manifold and having a. plurality of removable and interchangeable sides, means on one of said sides for connection to the carburetor, a duct for hot exhaust gases extending through said housing, and a plurality of spurs extending through the walls of said duct, each of said spurs comprising an elongated end projecting into the duct passageway, a tramversely flattened head projecting into the housing chamber, and an intermediate threaded portion, substantially as described.

5. A device as set forth in claim 4. in which the threads or the intermediate portion are at a high pitch to facilitate being driven into position, substantially as described.

6. A device as set forth in claim 4 in which the transversely flattened heads or the spurs are angularly disposed, as and 101' the purpose speci fled.
